[Skimmertalk] CW Skimmer Telnet command to set sampling rate?

Thu Oct 6 09:52:42 EDT 2016

I may be missing something, but why don't you use a 7 band QS1R and connect
to local telnet port with your logging software?

Both Writelog and HDSDR support OmniRig, and HDSDR will synchronize your K3
VFO A frequency with the HDSDR cursor, if that's what you're looking for.
